Cambodia Weather & Best Time to visit Cambodia

Before taking a trip to Cambodia, it’s wise enough to do a little research about Cambodia weather patterns and when is the best time to visit Cambodia. If you have yet to have an answer to your question, our article below will give you some ideas to make your trip to Cambodia even better. 

Cambodia Weather Overview

Cambodia has the simplest weather system amongst Asian countries. There are two distinct seasons but travelers can enjoy visiting Cambodia all year round. 

Mainly due to the unaltered altitude and latitude throughout the country, the weather patterns are the same in most parts which can be pretty easy for many travelers.

There are two distinct seasons – dry season which lasts from October to late April and wet season from May to late September. Within each season there are variations in temperature, with the final few dry months leading up to the wet season (March and April) and the early months of the wet season (May and June) usually being the hottest of the year with temperatures in excess of 35°C at times.

Humidity is at its highest during March and April whilst the coolest months of the year tend to be between October and December, however, this is cool for Cambodia but far from chilly with average temperatures hovering around 24°C-26°C.

The Dry Season in Cambodia

October – April/Early May

Cambodia’s dry season lasts from October to April, when the dry north-east monsoon arrives, characterised by hot wind blowing across the entire country. Whilst November to January are quite cool (high 20°C’s), by April the weather is scorching making early morning and late afternoon Angkor Temple tours, with a few hours by the hotel pool at lunchtime, the preference for many.

Thanks to the hot weather this is unsurprisingly the season when Cambodia’s tourist numbers peak.

In more remote parts, such as the northeast regions of Mondulkiri & Ratanakiri, the roads are at their best and journey times are shorter because of this. Kep and Sihanoukville on the south coast are popular during this season as they bask in the brilliant sunshine and sea conditions are very favorable.

The Wet Season in Cambodia

Early/Mid May – October

Cambodia’s wet season comes courtesy of the southwest monsoon and lasts from May to October, bringing with it almost 75% of Cambodia’s annual rainfall. Across Cambodia, throughout much of the rainy season, daytime temperatures average between 25°C and 27°C. The early months of the wet season (May – July) remain very hot with infrequent rainfall usually in the form of short downpours. In the latter months (late July – September) the rains tend becomes more constant and is heavy at times, especially in coastal and rural regions.

Travel in the more remote corners of the country, such as Mondulkiri & Ratanakiri, is almost impossible due to the state of the roads and journeys into the northeast are inadvisable during the peak wet season because of this. There is also very limited access to Bamboo Island (near Kep) due to high seas.

On the upside, traveling in monsoonal Cambodia does have its advantages. The dust is gone and the lush greenery of the countryside returns. Angkor Wat, in particular, is stunning in the wet season, with moats brimming with water and a severe drop in visitor numbers. High rainfall makes it the perfect time of year to visit the flooded forests and floating villages of Tonle Sap Lake by boat, as it swells to more than 5 times its size during wet season.
